No one was injured after a truck driver fell asleep at the wheel on Sunday morning, sending the rig veering across traffic and into a guardrail.

The accident happened on March 11th at approximately 5:20 a.m. in Victorville, California.

According to the California Highway Patrol, the tractor trailer hauling two cars inside its trailer was traveling on the northbound 15 Freeway south of Bear Valley Road when the driver fell asleep at the wheel, sending the rig drifting to the right shoulder. When the driver came-to, he over corrected and sent the truck veering across several lanes of traffic before striking the center divider, separating the cab from the trailer and sending the two cars crashing through the sides of the trailer.

“Once he woke-up he cranked the wheel to the left and went across all lanes of traffic before hitting the center divider and flipping over,” said CHP Officer M. Mumford to Victor Valley News.

A second crash between two passenger vehicles then occurred moments after the semi collided with the guardrail. Luckily, no one was injured in either of the collisions.

The northbound 15 Freeway was reduced to one lane and the southbound side was reduced to two near Bear Valley Road as crews worked to clear the wreckage from the collisions. The lanes were shut down for several hours but have since been reopened.

The name of the truck driver has not yet been released and the nature of the citations issued, if any, are not yet clear.
